To all whom it may concern:

Be it known that I, CARL G. NAY om'a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Mills for RollingFlanges, of which the following is a specification. I

My invention .relates to improvements in mills for rolling flanges.

One-of the especial objects of my invention is to provide a mill thatwill produce a flange, such as a pipe flange, from a ring of ductilematerial, such as soft iron or steel, by turning an axially disposedpart of the ring into radial planes at substantial right angles to theaxis of the ring.

Another object of my invention is to provide a mill that will roll theflange so produced to uniform thickness after it has been turned outfrom the ring into the desired plane.

Another object of my invention is to pro videa simple and cheaply'toconstruct mill capable of rapid manipulation and having a large capacityof output.

Other, further and more specific objects of my invention will becomereadily apparent, to persons skilled in the art, from a considerati onof the fOllOWing description when taken in conjunction with thedrawings, wherein Figure 1 is a plan view of the mill.

Fig. 2 is a central longitudinal section taken on line 22 of Fig. 1.

Fig. 3 is an end elevation showing the front edge of the mill.

Fig. 4 is an enlarged plan view of the face plate or chuck-bearing tableshowing parts of the flange chuck, in section.

Fig. 5 is a section taken on line 55 of Fig. 2.

Fig. 6 is a vertical central section similar to that shown in Fig. 2,.With the parts in different positions.

Fig. 7 is a section taken on line 7-7 of Fig. 6.

In all the views the same reference characters are employed to indicatesimilar parts.

In the selected embodiment of my invention the frame bed 10 isrectangular in plan, supported by side frame housing members 11 and 12.The side members are provided with legs 13 tosupport the mill. A crossframe member 14 ties the side frame members 11 and 12 together, securedthereto, as at 15 and 16. Another cross member 17 ties the slde members11 and 12 together, being connected to the upwardly extending pillars 18and 19, as. at 20 and 21, respectively. The cross member 17 carries ashaft bearing 22 for the power shaft 24. Another bearing 25, for theshaft 24, is provided upon the upper end of a vertical frame leg 26,which is provided with an inwardly and horizontally extending member 27that is bolted to the cross member 14, as at 28. The power shaft 24,which is rotatably mounted in the bearlngs 22 and 25, carrles twodriving, clutch pulleys 30 and 31. These pulleys, as usual,

are loose uponthe shaft 24, but capable of bein connected thereto,alternatively, by the riction clutches 32 and 33, respectively, when theintermediate clutch member 35 is shifted axially on'the shaft 24, forthe purpose. The clutch pulley 30 is to be driven in one direction by abelt, not shown, and the pulley 31 in like manner is to be driven in theopposite direction. By this arrangement the shaft 24 may be rotated ineither direction by selective operation of the.

clutches 32 and 33. The shaft 24 bears on its out-board end a gearedpinion 36 which is in driving mesh with the gear wheel 37. The gearwheel 37 is secured to a shaft, which finds support in the bearing 39projecting laterally from one side of the leg 26,

. and in the bearing 40 located upon the upper portion of the crossframe member 14. A

geared pinion 41 is loosely mounted on the shaft 38, and is adapted tobe connected to and disconnected therefrom by the clutch 42, when theclutch operating member 43 is shifted on shaft 38, for the purpose. Ashaft 44 is supported on frame 10 in bearings 45, 46

and 47 and on its rear outboard end it carries. a gear wheel 48 thatmeshes with the gear pinion 41. Secured to the shaft 44 and locatedbetween the bearings 45 and 46 is a worm 49. A segment 52 of the wormwheel 50 is in meshing driving relation with the worm '49. The geareddisk segment 50 is provided with a stub shaft 51 which is concentricwith the toothed'portion 52 of the segment. On the opposite side of themill is another shaft 44 and supports, which are similar in everyrespect to the shaft and the parts just described. These parts areindicated by the same reference characters with the addition of theexponent prime The stub shafts 51, 51' find support in the bearings 53,53 that are parts of the side frame members 11 and 12, respectively.

A yoke, or arm 55, has its ends 56 and 57 connected to one side of theaxis 51 of the worm disk segment, respectively, as at 58. A hearingsleeve 59 is slidable in a bore 60 made through the apex of the arm 55.The sleeve 59 carries a rotatable arbor, or shaft, 61, which carries onone end a flange-engaging roller 62, and on the other end a boss or head63-. The sleeve 59 is longer than the width of the arm 55 so that theroller 62 may be moved axially, either in a horizontal or verticaldirection, depending upon theposi-tion of the arm 55.

When the arm 55 is rotated, uponits stub-shafts 5151 by the operation ofthe worms 49'49 in engagement with the worm wheel segments 52-52, theouter edge of the roller '62 will be bodily moved bearings 73 and 74,which are slidable upon the shaft. The pinion is driven by a feather 79,carried by the pinion, and axially'movable in the spline 76.

The slidable plate extends upwardly, as at 79', to provide a hol'lowbossor hub to receive a vertically disposed sleeve 80. Mounted on the sleeve80, and secured thereto by a key way 81, is a beveled gear wheel 82,which meshes with the beveled pinion 77, driven by the shaft 38. It willbe observed that the ends of the pinion 77 are rotatably supported inthe bearings 73 and 74, so that should the shaft 38 be withdrawn fromthe pinion 77 it would be held in alinement by the bearings provided inthe boxes 73 and 74. The upper surface 83, of the beveled gear 82,provides a face plate or chuck receiving table, upon which is supporteda flange-engaging chuck 84. The table 83 is slotted at intervals, as at85, to provide for emplacement of relatively larger or smaller chucksthan that shown in the'dra'wings, which are to be held on the face plateby bolts 86 that pass through the slots 85. The chuck 84 is providedwith an annular concentric depression, within which is seated an annularreplaceable wearing ring 87 having .an inner diameter substantially thesame as the outer diameter of the flange sleeve or ring '88. A radiallydivided, tapered annular chuck member 89,

' shown in *Fig. '4 to contain four separated parts, are yieldingly heldtogether by a coiled spring ring 90, which is seated in a grooveextending around and in the said parts of the inwardly-tapered chuckring. Seated in the plural part tapered ring 89, is a reversely tapereddisk 91 which is secured at its axis to a vertically extending arbor 92.When the vertically disposed arbor 92 is moved downwardly, carrying thetapered chuck disk 91 with it, the latter will expand the tapered chuckring 89 into more intimate contact with the inner surface of the :flangering 88-againstthe wearing ring 87 of the chuck, thereby holding theflange ring firmly in the position in which it has been placed in thechuck. The lower. end, of the stem or arbor 92 is threaded, as at 93 fora'nut 94. The nut is freely rotatable around the arbor 92, and

is prevented from leaving the endth'ereof by the annular perforate plate95. Surrounding this nut is a friction brake band 96-, having itsopposite ends 97 and 98 connected to two vertically disposed parallelrotatable arbors 99 and 100, respectively. These arbors bear upon theirupper ends intermeshing gears,-or ,pinions 101 and 102, respectively. Ahandle or arm 103 extends forwardly and is employed for rotating thearbors 99 and 100 to tighten the brake band 96 around the nut 94.

The 0111101184 is provided with a vertically movable bottom plate 84'which carries on its outer .periphera-ledge a stop ring 87 upon theupper edge of which rests the flange ring 88 when it is placed withinthechuck 84. The thickness of this ring 87 will determine the extent towhich the ring 88 will project above the chuck, and serves asa means forejecting the ring 88 from thechuck when the flange has been formed.

The vertically movable stem 92 is provided wit-h a reduced portion 92thatpasses neatly through the plate 84 into thedisk 91. \Vhen the-stem92 is raised the shoulder 92 will engage the plate 84 and raise it andthe flange 88 so as to substantially eject the latter from the chuck.The operation of the chuck and flange ejector will be more fullyhereinafter explained.

Rotatably supportedbn the cross frame member 14 is a threaded shaft 105.The shaft is in threaded engagement with adepending lug 106 which issecured to the bottom of the plate 70, as by bolts 107. A

sleeve 108 is loosely rotatable upon the shaft an'd carries a sprocketwheel 109 and a friction disk clutch member 110. -The sleeve, disk andsprocket wheel are driven "by the sprocket chain 111, from. a sprocketwheel 112 secured to the shaft -38. Another relation,

Extending across the front of the mill and near the bottom thereof 'aclutch operating shaft 116 supportedin brackets 117 and 118 extendingfrom the base plate 10. A clutch-shifting lever 119 is secured to theshaft 116, as by a pin 120, so that when the lever 119 is moved, theshaft 16 is rocked. Another clutch operating lever 121 is looselysupported on the shaft 116, and has an extended end 122 therebelow,which is pivotally connected to a rearwardly extending rod 123. This rodis pivoted, as at 124, to a transversely extending arm 125 which issecured to the upright shaft 126, that has bearing in brackets 127 and128. An arm 129 is secured to the vertical shaft 126, as by a key 130,and is pivotally connected to the axially movable clutch shifting member 35.

An arm 132 is secured to the shaft 116, as at 133, and is pivoted to areciprocatable rod 134 that is supported in brackets 135 and 136, therear end of which is pivoted, as at 137, to an upwardly extending lever138.

i This clutch shifting lever 138 is pivoted to the frame, as at 139,.the upper end of which, 140, engages the axially movable clutch element43 to connect and disconnect the clutch 42 with the pinion 41. The armis provided with a V-shaped notch 141, which communicates with the borein which the sleeve 59 is axially movable. The sleeve 59 is providedwith a rack 142, on one side, into which meshes a geared pin-- ionsegment 143 which is, preferably, part of the lever 144, and which ispivoted as at 145, to a pin 147, to retain the geared segment in meshwith the rack. The lever 144 bears on its outer end, a head 148, throughwhich passes an operating pin 149. The pin bears a flange 150 againstwhich presses an open helical spring'151 to press with some yieldingeffect the end of the pin 149 against the inside surface of the flange152.

The bore 153 is shown in Fig. 6, but the pin 149 covers the oppositebore in the'fiange 47 in which the pin is now located. a When the pin149 is in the bore 154, as shown in Fig. 6, the sleeve 59 has been movedout of the bore60 to its farthest extent by operation of the gearedsegment 143 in coiiperation with the rack 142 and when the arm 144 isturned to the left, the geared segment 143 in. cotiperation with therack 142 will -.move the sleeve 59 back into position so that the roller162 may be raised or lowered when its axis is in a vertical plane.

Therod 160 for operating clutch 110--114,

- passes through ears 161 and 162 projecting .provided with a heel.piece- 64 which normally bears on the front surface of the car 161 andholds the handle 163 in an upwardly inclined position. The inner end ofthe rod 160 is connected to a clutch operating le'ver164 that ispivoted, as at 165, and has an inwardly extendingend 166 that slides theclutch member 114 into contact with a the clutch-operating member 35into association with the clutch 33, thereby c0nnecting the clutchpulley 31 to the shaft 24. This causes the pinion 36, fixed to the shaft24 to rotate the gear wheel 37 which is secured to the shaft 38. Now thesleeve 108 surrounding the shaft 105 is beinglrotated by the shaft 38through the instrumentality of the link, belt 111 and its associatedsprocket wheels. Pressure is now applied to the upper end of the handlever 163, which moves the friction disk 114, rotatably' secured to theshaft 105, to make driving contact with the friction disk 110,,which isdriven by the sprocket belt 111, thereby rotating the screw 105 andmoving the table 70, and supported partsmutwardly, upon its ways 71. Thebearing boxes 72 and 7 4, and thepinion 77, move outwardly with the bedand these parts do not leave, entirely,

their engagement with the shaft'38.v As the spline 76 is cut to the endof the shaft 38, the feather 79 will move therein and the pinion willremain in rotative engagement with the shaft through the feather 79 andwill be supported in alinement by the bearing boxes 73 and 74, if theshaft 38 was entirely withdrawn. When the table 70 moves outwardly, itcarries with it the face plate 83, and the chuck 84 whichissecured onthe working surface thereof. It is now desir-- able to raise the sleeve59 so as to lift the roller 62 above the chuck 84 to facilitate theremoval of a flange and the emplacement of a ring 88 in the chuck. Thepin 149 is then pulled outwardly until it leaves the perforation 154 inthe flange 152, after which the arm 144 is moved over until the pin isin register with the perforation 153 in the flange. This will rotate thepinion 14".?) that is in mesh with the rack 142, and lift the sleeve 59,together with the roller 62. A new sleeve 88, of which a flange is to bemade, is now inserted in the chuck and the lever 103 is grasped so as todraw the brake band 96 tightly around the screw nut 94. This willfrictionally engage-the nut and. hold'it still while the sleeve'80 andstem 92 are being rotated. The nut, by this operation, will pull'downthe stem 92, upon the upper'end of which the tapered chuck disk 91 issecured, thereby causing the disk 91 to press the divided members ofchuck ring 89 outwardly into firm engagement with the rin 88, of which aflange is to be made; The plate 84 and stop ring 87 will be in positionsshown in Fig. 2 when the shoulder 92 is below the upper surface of thework table 83. The sleeve or ring 88 is placed in the chuck with itslower edge resting on the stop ring 87 and the plate 84 in its lowermost position. The chuck may then be closed by pressing the disk 91firmly into contact with the chuck member 89 as heretofore described.

The chuck-operating lever 121 is now moved in the opposite direction,whereupon the pulley 30 is connected to the shaft 24 through theinstrumentality of the friction clutch 32 and the pulley 31 isdisconnected therefrom. This will rotate the shaft 24 in oppositedirection and consequently it will rotate the shaft 38 in the oppositedirection. Now if pressure is again applied to the lever 163 the clutchmembers 110 and 114 are brought into connection and the screw 105 isrotated in direction reverse from its former operation, thereby causingthe table to be returned to its operative position. It is assumed thatthe arbor 61 and the roller 62 are now substantially in the positionshown in Fig. 2, with the exception that they have been elevated by thedepression of the arm 144. Now the arm 144 is moved back to the positionshown in Fig. 2, which has the effect to lower the roller 62 to theproper position to engage the inner surface of the ring 88, of which theflange is to be made. So soon as the clutch operating lever 163 isreleased, the friction disks 110 and 114 will no longer be held insufficient contact to rotate the screw shaft 105 and therefore the tablemay be stopped at any position desired in its forward and backwardmovement, by simply releasing the handle 163. Now when the clutch lever119 is moved outwardly, this will push the rod 134 rearwardly, causingthe end 140 of the lever 138 to move the clutch shifting lever 43 so asto cause the friction clutch 42 to connect the pinion 41 of the shaft38. This will rotate the shafts 44, 44 thereby rotating the gearedsegment disks 5050 so that their top surfaces will be carried to the riht, as viewed in Fig. 2, and as shown in dotted lines in Fig. 6. Theshaft 38, now rotating, causes the beveled geared pinion 7 7 to rotatethe gear wheel 82, upon which the chuck 84 is mounted, and thereby thering 88, of which a flange is to be made. The roller 62 contacts theflange ring 88 just above the upper surface of the chuck 84, andthereabove, presenting maximum surface engagement, and as the roller 62is bodily moved around the axis 51, upon which it is rotated, the uppersurface of the ring 88 is thereby deflected outwardly,

as shown in Fig. 6, until the axis of the rolle direction as to causethe roller 62 to be bodily moved to a position with its axis in a vertical plane, and while this movement is progressing the direction ofrotation is proper to rotate the screw shaft 105 to move the table 70outwardly, from its operative position, to more easily remove thefinished flange from the chuck, in which it has been secured and therotation of the table 83 is then such that the application of the brakeband 96, by pressure upon the lever 103, tends to loosen the nut 94 onthe lower end of the stem 99 and permit disengagement of the clutchmembers 89 and 91 to facilitate removal of the finished flange, which isprac-' part to engage the outer surface of a ring;

a radially expanding chuck member to engage the inner surface'of thering; a stop, for said ring, to permit a part'of the ring to extendoutwardly beyond the face of the chuck; a disk having a tapered edgeforengaging the inner expandible member of the chuck; a stem secured tothe disk to draw it into said expandible member; a nut on the stem;means to manually hold the nut from rotation; means to rotate said chuckmembers stem and ring; a roll for engagement with the inner surface ofthe outstanding part of the ring, and means to rock the roll while thering is being rotated, to roll the outstanding part of the ring intoasubstantial radial plane.

2. A flange rolling mill comprising a chuck to receive a ring; avertically movable, ring-receiving stop within the chuck; a rotatabletable to receive the chuck; apart rotatable with the table, to open andclose the chuck when its rotation is stopped and an impositive means tostop rotation of the part.

3. A flange rolling mill comprising a chuck to receive a ring; avertically movable ring-receiving stop and ejector, within the chuck; arotatable table upon which the chuck is axially mounted; a partrotatable with the table to open and close the chuck when its rotationis stopped and to vertically move said ejector and means to stoprotation of said part.

4. A flange rolling mill comprising a band-engaging flange-roller havina vertical axis; means for rotating said roller transversely of its axisin contact with the band; a band or ring-holdings chuck having avertical axis about which it is rotatable while holding the band incontact with the roller; means for rotating the chuck; means for bodilymoving the chuck forwardly out of working position while rotating, andmeans for automatically disengaging the flange after its bodily movementhas begun.

5. A flange rolling machine comprising a flange roller having a normalvertical axis; means for bodily moving the roller to a position with itsaxis in a substantially horizontal plane; a band-receiving chuck havingits axis in a vertical plane; means to rotate the chuck in a givendirection while the roller is turning the flange on the band; powermeans to tighten the chuck while rotating in said tion of rotation ofsaid chuck operating means to open the chuck.
